How to use this calculator
- Enter stall speed. Use the relevant 1g stall speed.
- Enter load factor. Use the positive limit load factor to screen.
- Read corner speed. The calculator multiplies stall speed by the square root of load factor.
- Compare with envelope. Use aircraft-specific data for certified envelopes.
How it works
The simplified positive corner-speed relation is corner speed = Vs x sqrt(n).
Pair it with V-n diagram, maneuvering speed and load factor from Va.
Worked example
Verified against the live calculator
A 50 kt stall speed with a 3.8 g limit load gives 50 x sqrt(3.8) = 97.5 kt.
Frequently asked questions
What is corner speed in this calculator?
It is the simplified positive corner speed where the stall curve reaches the entered limit load factor.
Is corner speed the same as Va?
For this simplified positive-side arithmetic, it uses the same Vs x sqrt(n) relation often used for Va screening.
Does this create a full V-n diagram?
No. Use the V-n diagram calculator for the simplified envelope chart.
Can this replace aircraft limitations?
No. Use approved aircraft data and limitations.
Method & assumptions
- Uses only the positive-side stall curve and entered limit load factor.
- Does not include gust envelopes, negative limits, Vne, certification details or aircraft-specific data.
